(googling the Turkish had a URL with tr-tr in it rather than en-us... changing the URL was better than using Google Translate).
So, basically it's the old: "Exception has been thrown by the target of an invocation"
There's still an outside shot that it simply isn't finding the R tools at all; the Admin installer puts things in Program Files, whereas the NonAdmin version puts things in User/Local (or some such)... it could explain this sort of error (e.g. Admin Alteryx won't find NonAdmin Predictive tools and vice versa, I don't think), so is worth checking.
@Atabarezz, did you have a version of the R 3.2 series already on your machine to which you installed packages? If yes, you may have an old version of a package in your presonal R library which is causing a failure in loading the name space of a package that Alteryx relies upon. By default, R first looks for packages in the user's personal library, and then goes to the system packages (which are the one you installed with Alteryx). As a result, if you have duplicate versions of the same package, it will use the one in your personal R library. Your personal R library should be C:\Users\<your user name>\Documents\R\win-library\3.2\
@Atabarezz, we have not seen this error before. What we need to do is see if we can replicate. The error is not between Alteryx and R, or on the R side in terms of package name collisions between different versions of a package. Rather, it seems to be an issue with the R tool itself. We are in the process of digging into this.
It is very strange. The closest incident I've seen to this was back when I was a university professor, and some students in that class were having really strange issues with the software we were using in the course. The students who had the problem all had their Windows machines setup to use Simplified Chinese as the language. There were no problems with any other languages (including Classical Chinese). I'm wondering if this might be a similar situation, except involving Turkish rather than simplified Chinese. It is a long shot, but it is one thing I can think of.
